Radar on Specialty Pharmacy

The FDA approved the first biosimilar in 2015, and since then, almost 50 more have been greenlighted. Last year saw the biggest influx of these competitors onto the U.S. market, and a recent Cardinal Health report, titled 2024 Biosimilars Report: Insights on a pivotal year of evolution and expansion, highlights this burgeoning market.

Since 2015, biosimilars have saved $23.6 billion, with $9.4 billion of that total coming in 2023 alone. Last year saw the long-awaited competition to the top-selling Humira (adalimumab) from AbbVie Inc., with nine biosimilars launching, two of them with interchangeable status, an important differentiator to providers. “As the top-selling drug in the world with annual sales of $20 billion in 2022, the potential monetary impact of increased market competition cannot be overstated,” says the report.

Late last year, the FDA approved a new regimen for urothelial cancer that could transform the treatment of the condition, according to industry experts. However, the cost of the combination — which is estimated to be more than half a million dollars annually — could pose a barrier to its uptake.

On Dec. 15, 2023, the FDA approved Pfizer Inc. and Astellas Pharma Inc.’s Padcev (enfortumab vedotin-ejfv) in combination with Merck & Co., Inc.’s Keytruda (pembrolizumab) for the treatment of people with locally advanced or metastatic urothelial cancer (la/mUC). The agency gave accelerated approval to this combination for people with la/mUC who are not eligible for cisplatin-containing chemotherapy on April 3, 2023. The newest approval converts that accelerated approval to full and expands the labeled indication to include the treatment of people eligible for cisplatin chemotherapy. The application had priority review and breakthrough therapy designation.

Feb. 9: The FDA approved Aurobindo Pharma Limited’s deflazacort for the treatment of Duchenne muscular dystrophy (DMD) in people at least 5 years old. The corticosteroid is the first generic of PTC Therapeutics, Inc.’s Emflaza that the agency has approved. It has approval as a tablet for all of Emflaza’s dosage strengths: 6 mg, 18 mg, 30 mg and 36 mg. Emflaza also is available as an oral suspension. That agent is approved for the treatment of DMD in people at least 2 years old; it has exclusivity for the treatment of people ages 2 to 5 years old until June 2026. The recommended daily dosing is 0.9 mg/kg. Drugs.com lists the price of 30 18 mg tablets of Emflaza as more than $9,706.

Feb. 9: The FDA approved Takeda Pharmaceuticals U.S.A., Inc.’s Eohilia (budesonide) for the treatment of people at least 11 years old with eosinophilic esophagitis. The corticosteroid is the first and only FDA-approved oral treatment for the indication. Recommended dosing is 2 mg twice daily for 12 weeks; the agent is available in 2 mg/10 mL single-dose stick packs. Its monthly wholesale acquisition cost is $1,875.

Coherus BioSciences, Inc. launched its Udenyca Onbody, an on-body injector (OBI) presentation of Udenyca (pegfilgrastim-cbqv), the company said Feb. 21. The OBI is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in people with nonmyeloid malignancies receiving myelosuppressive anticancer drugs associated with a clinically significant incidence of febrile neutropenia. Udenyca was first approved Nov. 2, 2018, and the leukocyte growth factor is one of six biosimilars of Amgen Inc.’s Neulasta (pegfilgrastim) that the agency has greenlighted. A health care provider must fill the OBI with the co-packaged syringe and apply it to the patient’s abdomen or back of the arm. About 27 hours after it is applied to the skin, the OBI will deliver a 6 mg/0.6 mL dose of Udenyca over about five minutes.

Catalyst Pharmaceuticals, Inc.’s Agamree (vamorolone) is now available in the U.S., the company said March 13. The FDA approved the first-in-class corticosteroid on Oct. 26 for the treatment of Duchenne muscular dystrophy in people at least 2 years old. The company is offering the comprehensive support program Catalyst Pathways Patient Assistance Program for Agamree for eligible patients. Drugs.com lists the price of 40 mg/mL oral suspension as more than $10,013.

An ongoing lawsuit over the use of copay accumulators is drawing to a close following the defendants’ and plaintiffs’ motions to dismiss their appeals. The ball is now in the federal government’s and state insurance commissioners’ courts to enforce a district court judge’s ruling, which states that manufacturer assistance must be counted toward patients’ out-of-pocket responsibility unless a brand-name drug has a medically appropriate generic equivalent.

Health plans and PBMs several years ago began implementing copay accumulators — and then a new iteration known as copay maximizers that declare certain drugs non-essential health benefits to avoid covering them per the Affordable Care Act (ACA) — to counter manufacturer copay assistance programs. Before these tools, that assistance would count toward beneficiaries’ annual out-of-pocket expenses. When those out-of-pocket maximums were reached, health plans would cover the remainder of members’ costs for the year. With accumulators and maximizers, patients can still use that assistance, but it does not help reduce those out-of-pocket costs.
